The pulling force being applied plus the pipe in process of deployment/cable body deadweight and stretcher, both are superimposed the tension and torsion of formation
Load easily causes umbilical and destroys.Therefore, the mechanical property under compound action is reversed in ocean engineering flexible pipe cable section in stretching
It is one of important design parameter.In order to study umbilical tension-torsion mechanical behavior feature and verify whether its intensity reaches design and want
Ask, thus there is the probability destroying under tension and torsion during reducing use；Umbilical is carried out to it in laboratory domestic demand before being on active service
Tension and torsion is tested.On the one hand test is provided to support for research umbilical mechanical mechanism, on the other hand its measurement result will be used as weight
The mechanical performance index wanted.
Ocean engineering compliance umbilical is made up of building blocks of function and mechanical property stiffener, twines for typical multi-layer helical
Around structure, usual bore 100mm-500mm；General flexible duct bore is greater than extra large cable or umbilical cables, and due to it
Also have external pressure and tensile load in some metal level opposings, therefore its torsional rigidity is larger.Extra large cable and umbilical cables torsional rigidity are big
Cause scope is 10-100knm2, and the usual scope of flexible duct torsional rigidity is 1000-3000knm2.Testing machine is mostly right at present
The independent torsion of material test specimen or umbilical structure or extension test, lack tension and torsion experimental provision.Meanwhile, found according to investigation
Existing applying torquer on market, whether electric power hydraulic-driven, although its output torque disclosure satisfy that extra large cable or
Umbilical cables require, it can be difficult to realizing effective torsion of flexible duct.Especially, when needing to test maximum twist angle, with
The increase of corner, the umbilical of spiral winded type by effect of holding with a firm grip, for the moment of torsion that overcomes its resistance to need to apply also gradually
Increase.Additionally, umbilical has coupling effect under tension and torsion effect, on market, the experimental provision of molding is difficult to meet this mechanics
The research of mechanism.
